Anthurium Plant Named &#39;ARAANTPIN1&#39;

ABSTRACT

‘ARAANTPIN1’ is a new and distinctive variety of  Anthurium  which is characterized by large and attractive inflorescences consisting of a vibrant pink spathe with a nearly horizontal aspect and a white spadix with a yellow apex, dark green and glossy foliage, and the stability of all characteristics from generation to generation. The new variety is typically produced as an indoor ornamental plant.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rightsapplication number 2016/0697, filed Mar. 10, 2016, which is hereinincorporated by reference.

Latin name of the genus and species: The Latin name of the genus andspecies of the novel variety disclosed herein is Anthurium andraeanumLinden ex Andre.

Variety denomination: The inventive variety of Anthurium disclosedherein has been given the variety denomination ‘ARAANTPIN1’.

BACKGROUND OF THE INVENTION

Parentage: The new cultivar is a seedling selection which resulted fromthe controlled pollination of Anthurium andraeanum ‘K52’, the seedparent, and Anthurium andraeanum ‘K24’, the pollen parent. Both parentsare developed and owned by the inventor and were never commerciallyreleased. Said cross was performed by the inventor in De Lier, TheNetherlands, in June of 2013. Seeds were harvested from ‘K52’, sown, andgrown to maturity in order to evaluate for unique characteristics whichmay be of commercial value. In September of 2014, after evaluating theseedlings for approximately one and a half years, one progeny wasobserved to exhibit good plant vigor with a unique combination of large,vibrant pink flowers and attractive foliage. In November of 2014, afterfurther evaluation to confirm the unique characteristics, the newcultivar was selected for commercialization and given the breederdenomination ‘ARAANTPIN1’.

Asexual Reproduction: Asexual reproduction of ‘ARAANTPIN1’, by way ofmeristematic tissue culture, was first performed in November of 2014 ata laboratory in De Lier, the Netherlands. Four successive generations soproduced have shown that the unique features of the instant cultivar arestable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘ARAANTPIN1’ has not been observed under all possibleenvironmental conditions and the phenotype may vary somewhat withvariations in the instant environment such as temperature, day length,and light intensity, without, however, any variance in genotype. Thefollowing characteristics have been repeatedly observed and representthe distinguishing characteristics of the new Anthurium cultivar‘ARAANTPIN1’. These traits, in combination, distinguish ‘ARAANTPIN1’ asa new and distinct cultivar.

-   -   1. Anthurium ‘ARAANTPIN1’ is a robust, moderately vigor        herbaceous perennial with a broad, upright growth habit; and    -   2. Anthurium ‘ARAANTPIN1’ exhibits dark green, glossy foliage        with a moderately narrow cordate shape; and    -   3. Anthurium ‘ARAANTPIN1’ exhibits a large inflorescence,        presented at and slightly above the foliage; and    -   4. Anthurium ‘ARAANTPIN1’ exhibits a vibrant pink spathe with a        nearly horizontal aspect and a white spadix with a yellow tip.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of a new and distinctvariety of Anthurium known as ‘ARAANTPIN1’, based upon observations madefrom a sample set of plants grown in 9 cm nursery pots which wereapproximately one year old from a rooted cutting. Plants were grown in agreenhouse in De Lier, The Netherlands, utilizing conventionalgreenhouse production protocols for Anthurium, which consisted ofregular irrigation by way of ebb and flood watering benches andfertilizer applications of a complete fertilizer with micro nutrients atan EC value ranging from 1.0 to 1.8. No chemical pest or diseasemeasures were utilized in production. Young plants are assimilated tothe greenhouse under shade cloth and later move to light levels rangingfrom 3000 to 4000 lux for the final 5 months of production. Observationdata was recorded in February of 2017.

Those skilled in the art will appreciate that certain characteristicswill vary with older or, conversely, with younger plants. ‘ARAANTPIN1’has not been observed under all possible environmental conditions. Wheredimensions, sizes, colors and other characteristics are given, it is tobe understood that such measurements are approximations or averages setforth as accurately as practicable. The phenotype of the variety maydiffer from the descriptions set forth herein with variations inenvironmental, climactic and cultural conditions. Color notations arebased on The Royal Horticultural Society Colour Chart, The RoyalHorticultural Society, London, sixth edition.
